How to solve sin(z)=2 (Complex Analysis)

The problem wants me to solve sin(z)=2 by equating the real and imaginary parts.

Using , the definition of sin(z), and some algebra, I've gotten as far as:.
This is where I'm stuck. I know I'll have to set the imaginary part to 4 and the real part to 0, but how do I separate them from this point...?
